Description
Technical field
The present invention relates to data wireless links transmission technology in Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, the method for receiving terminal send window size adjustment information (WindowSize SUFI) in particularly a kind of data wireless links transmission.
Background technology
Radio link control in the WCDMA system (RLC) is being controlled the transmission of data wireless links bag.Rlc protocol is a kind of control protocol based on sliding window, and referring to Fig. 1, Fig. 1 is a rlc protocol sliding window schematic diagram.Wherein, the RLC transmitting terminal has the square of the oblique line of reporting to the leadship after accomplishing a task to be meant that the opposite end confirms not received that the packet that need resend, hypographous square represent the packet of waiting for that the opposite end is confirmed, and blank square is represented the buffer memory that do not take.The RLC receiving terminal has the square of the oblique line of reporting to the leadship after accomplishing a task to represent that the opposite end sends to lose the packet that need receive again, and hypographous square represents that the packet received, blank square represent the buffer memory that does not take.The rlc protocol basic variable is described as follows:
Configured_Tx_Window_Size: the upper-layer protocol layer disposes the initial value to the send window of RLC transmitting terminal, also is maximum send window size.Unit represents with the number of protocol Data Unit (PDU).The RLC transmitting terminal sends buffer memory according to this variable application.
Configured_Rx_Window_Size: the upper-layer protocol layer disposes the size to the initial receive window of RLC receiving terminal.Unit represents with the number of PDU.The RLC receiving terminal receives buffer memory according to this variable application.
VT (S): send state variable.The sequence number of the next PDU that indicates to send (removing the PDU of re-transmission).
VT (A): confirm state variable.The sequence number of representing the continuous PDU that next wait receiving terminal is confirmed.
VR (R): accepting state variable.The sequence number of the next continuous PDU that indicates to receive.
VR (H): best expectation accepting state variable.The sequence number of the highest PDU that expression expectation receives.
VT (MS): maximum send state variable.The PDU sequence number will not allow to send more than or equal to this value.
VT(MS)＝VT(A)+VT(WS)。
VT (WS): the size of send window.Initial value also is that maximum is Configured_Tx_Window_Size, and minimum value is 1 (or value of other upper-layer configured), and VT (WS) changes in this scope.
VR (MR): the maximum state variable that allows reception.The sequence number of PDU will be rejected by the RLC receiving terminal more than or equal to this value.VR(MR)＝VR(R)+Configured_Rx_Window_Size。
The RLC receiving terminal is received by some bag of status PDU (Status PDU) notice RLC transmitting terminal, some bag is not received, and after the RLC transmitting terminal is received these status PDU, changes the value of VT (A), thereby promote VT (MS) to front slide, guarantee that data constantly are sent out.When the RLC transmitting terminal detect certain PDU be not received the end receive that the square of cross hatching is arranged as RLC transmitting terminal among Fig. 1.That will cause VT (S) constantly to increase up to VT (MS), no longer sends sequence number more than or equal to the data of VT (MS).When detecting certain PDU, the RLC receiving terminal do not receive the cross hatching square is arranged as RLC receiving terminal among Fig. 1.Will cause VR (H) constantly to increase up to VR (MR) so, no longer Receive sequence number is more than or equal to the data of VR (MR).
Regulation RLC receiving terminal is according to the reception condition of self in the rlc protocol of version at present, and major part is that the situation that receives buffer memory is controlled the size of RLC transmitting terminal send window, thereby the bandwidth of controlling Radio Link is used.Use the status PDU that comprises Window Size SUFI to carry out flow control in the agreement,, improve the service efficiency of wireless link bandwidth to adapt to the variation of wireless environment.
According to agreement, usual way is that receiving terminal comprises Window Size SUFI information in Status PDU, sends to the transmitting terminal of RLC.Formation such as the table one of Window Size SUFI:
| ????TYPE |
| ????WSN |
Table one
Wherein, TYPE: information type parameter.Length 4bit is worth and is: 0001, and expression is a WINDOWSUFI information.WSN: send window size parameter.Length 12bit is worth and is: the window size that the RLC receiving terminal is filled in according to self reception condition.After receiving the Status PDU that comprises Window Size SUFI information when the RLC transmitting terminal, VT (WS) is changed into WSN in the Window Size SUFI information, if WSN=0, then this SUFI abandons; If WSN＞Configured_Tx_Window_Size, then VT (WS) gets Configured_Tx_Window_Size.Can change the size of send window by this method, avoid the bandwidth usage decrease in efficiency and the data congestion of data link.
Referring to Fig. 2, Fig. 2 changes the send window schematic diagram for receiving terminal by Window Size SUFI information notice transmitting terminal.As shown in Figure 2, when the RLC receiving terminal detect receive buffer memory free space in continuous increase, when reaching some threshold value, for example the bag of all re-transmissions is received among Fig. 2, when the RLC receiving terminal does not have buffer memory to take.The RLC receiving terminal sends the Status PDU that comprises WindowSize SUFI information to the RLC transmitting terminal, and the WSN in the Window Size SUFI information is greater than the VT (WS) of current transmitting terminal, and by Window Size SUFI, notice RLC transmitting terminal increases VT (WS).
After the RLC transmitting terminal is received this Status PDU, VT (WS) is changed into WSN in the Window SizeSUFI information, strengthen send window, avoid the bandwidth usage decrease in efficiency of data link.
When Radio Link worsens, have loss of data, cause the free space of RLC receiving terminal buffer memory to reduce, the RLC receiving terminal sends by the data that Window Size SUFI reduces the RLC transmitting terminal this moment, notice RLC transmitting terminal reduces VT (WS), thereby reduces send window, avoids the congested of data.
The wireless link bandwidth operating position is not monitored according to agreement regulation transmitting terminal, only when receiving the Window Size SUFI information that receiving terminal sends, adjust window size according to information requirements, if the Window Size SUFI of receiving terminal transmission loses like this, transmitting terminal just can initiatively not carry out the window adjustment.At chain route badness when good state transforms, in case the RLC receiving terminal requires the RLC transmitting terminal to increase send window Window Size SUFI information dropout, transmitting terminal does not carry out the window adjustment, the triggering of Window Size SUFI does not have unified standard in rlc protocol, just might be after triggering once after just triggering for a long time, especially improve at wireless quality, trigger under the situation that packet loss descends even no longer, in that even Radio Link is good during this period of time, Radio Link also may will cause the speed of very serious Radio Link to descend by very low rate sending data.
Actual measurement situation by different business, the PDU loss ratio of some non-real-time data business can tolerate 10%, and under the good wireless environment, the loss ratio of agreement regulation is no more than 0.7%, so the probability that Window Size SUFI loses is higher comparatively speaking.
According to above description as can be known, in the wireless transmission process, lose, will cause the speed of the congested or Radio Link of data to descend if notice RLC transmitting terminal carries out the Window Size SUFI information of send window adjustment.
At present, the method for receiving terminal transmission Window Size SUFI information mainly contains following two kinds:
First kind: the method that periodically sends Window Size SUFI information.Adopt at present usually this kind method, this method is all pressed the timer T cycle at whole RLC receiving entity and is sent WindowSize SUFI in running time, wither away up to the RLC receiving entity.Can guarantee substantially that like this RLC transmitting terminal receives Window Size SUFI information, and carry out Flow Control normally.
Second kind: the method that must comprise Window Size SUFI information among the Status Report.This method must comprise that TYPE is 0001 Window Size SUFI information in Status Report.Because the frequency that Status Report sends is higher, receives WindowSize SUFI information so also can guarantee the RLC transmitting terminal, and carries out Flow Control normally.
Above-mentioned two kinds of methods, though can both carry out normal Flow Control, but receiving terminal all is repeatedly to repeat to send Window Size SUFI information blindly in two kinds of methods, and send window does not need to adjust in fact in some cases, make the Window Size SUFI information that wherein sends many times there is no need, so just wasted valuable interface-free resources.
As seen, since comparatively simple in the agreement for Window Size SUFI triggering and application argumentation, there is not to propose relevant safeguard measure yet.Caused the waste of interface-free resources in the application process of reality, made the utilization ratio of wireless link bandwidth reduce, even rlc protocol has been deteriorated to stop---etc. agreement, very big for the application influence of transfer of data.
